PREFACE
This manual is the alarm/parameter guide required to use the EZMotion-NC E60/E68 Series.
This manual is prepared on the assumption that your machine is provided with all of the EZMotion-NC
E60/E68 Series functions. Confirm the functions available for your NC before proceeding to operation by
referring to the specification issued by the machine manufacturer.
Notes on Reading This Manual
(1) This manual explains general parameters as viewed from the NC.
For information about each machine tool, refer to manuals issued from the machine manufacturer.
If the descriptions relating to "restrictions" and "allowable conditions" conflict between this manual
and the machine manufacturer's instruction manual, the later has priority over the former.
(2) This manual is intended to contain as much descriptions as possible even about special operations.
The operations to which no reference is made in this manual should be considered impossible.
Caution
If the descriptions relating to the "restrictions" and "allowable conditions" conflict between this
manual and the machine manufacturer’s instruction manual‚ the latter has priority over the
former.
The operations to which no reference is made in this manual should be considered
impossible.
This manual is complied on the assumption that your machine is provided with all functions.
Confirm the functions available for your machine before proceeding to operation by referring
to the specification issued by the machine manufacturer.
In some NC system versions‚ there may be cases that different pictures appear on the screen‚
the machine operates in a different way or some function is not activated.
Precautions for Safety
Always read the specifications issued by the machine maker, this manual, related manuals and attached
documents before installation, operation, programming, maintenance or inspection to ensure correct use.
Understand this numerical controller, safety items and cautions before using the unit.
This manual ranks the safety precautions into "DANGER", "WARNING" and "CAUTION".
DANGER
When the user may be subject to imminent fatalities or major injuries if handling is
mistaken.
WARNING
When the user may be subject to fatalities or major injuries if handling is mistaken.
CAUTION
When the user may be subject to injuries or when physical damage may occur if
handling is mistaken.
Note that even items ranked as "
CAUTION", may lead to major results depending on the situation. In any
case, important information that must always be observed is described.
DANGER
Not applicable in this manual.
WARNING
Not applicable in this manual.
CAUTION
1. Items related to product and manual
If the descriptions relating to the "restrictions" and "allowable conditions" conflict between this
manual and the machine manufacturer’s instruction manual‚ the latter has priority over the former.
The operations to which no reference is made in this manual should be considered impossible.
This manual is complied on the assumption that your machine is provided with all functions.
Confirm the functions available for your machine before proceeding to operation by referring to
the specification issued by the machine manufacturer.
In some NC system versions‚ there may be cases that different pictures appear on the screen‚
the machine operates in a different way on some function is not activated.
2. Items related to faults and abnormalities
If the BATTERY LOW alarm is output, save the machining programs, tool data and parameters
to an input/output device, and then replace the battery. If the BATTERY alarm occurs, the
machining programs, tool data and parameters may be damaged. After replacing the battery,
reload each data item.
[Continued on next page]
CAUTION
[Continued]
3. Items related to maintenance
Do not replace the battery while the power is ON.
Do not short-circuit, charge, heat, incinerate or disassemble the battery.
Dispose of the spent battery according to local laws.
4. Items related to servo parameters and spindle parameters
With the MDS-C1 Series, only the serial encoder is compatible as the motor side detector. The
OHE/OHA type detector cannot be used as the motor side detector.
Do not adjust or change the parameter settings greatly as operation could become unstable.
In the explanation on bits, set all bits not used, including blank bits, to "0".

When manually returning to the
reference point‚ the return direction
differs from the axis movement direction
selected with the AXIS SELECTION
key.
• The selection of the AXIS SELECTION
key’s +/– direction is incorrect. The error
is canceled by feeding the axis in the
correct direction.
0004

release it first.
• An axis that can be removed has been
issued‚ so perform the correct
operations.
• The command is issued in the same
direction as the direction where manual
skip turned ON‚ so perform the correct
operations.
• During the manual/automatic simul-
taneous mode‚ the axis commanded in
the automatic mode became the manual
operation axis. Turn OFF the manual/
automatic valid signal for the
commanded axis.
• Turn ON the power again‚ and perform
absolute position initialization.
